ImgMap

ImgMap: Render any image on an in-game map!

By Evangon, Maximvdw, and JohnnyBlu

Originally coming from a picture of a troll face by md_5, this plugin allows a user with a map in hand (obviously with the proper permissions) to essentially put an image onto the map.
The image could be anything: Instructions, rules, messages, warnings, a very nice picture of a cat, whatever you want! All images are resized to the proper dimension of 128x128. The image is then sent over to a rendering process (Devs: Check the source on how it's done if you want), which then the map renders the image for that map. Anyone with a map with the same ID (Typically, it says when you hover over it, e.g "Map #0") to see the same image too! The only downside to all of this is that due to the nature of Minecraft maps, they do not support full color. This is due to a limitation on the clients themselves.

Installation

Just drop it into the /plugins/ folder! No special configuration needed!

How to use

Give yourself a map with a specific ID. This ID can be anything, but remember, once you draw an image on it, it will pertain only to that specific ID!

Get the URL of the desired image! This is where some people mess up. In order for the plugin to successfully render it, it has to be a direct link to the image. Simply right click on the image and hit "Copy Image Location".

Hold the map with the super specific ID and type in "/drawimage" and paste it! For most users, to paste, you do "CTRL+V".

Wait a bit; rendering can take a bit. You'll notice several segments appear on the map; this it indicating that it's loading.
If nothing happens, you're either met with a message that says something along the lines of "Server Internal Error" or you're staring a blank map. If you get kicked with the message with "Server Internal Error", simply type, in console, "fixmap <your super specific id>". This basically fixes the map with the old over world rendering. Try again; if it doesn't work, report it in the comments!
However, if you are getting nothing, be sure the image is accessible directly from your browser (clear your cache before you do so!) Sometimes, what happens is that the owner of the website has set privileges denying anyone from accessing the image directly. A bit bothersome, but you can probably save the image and upload it somewhere else. However, when doing so, please follow the copyright usage on said images!

Viola! Your map now has that pretty picture of a kitty or something!

Commands

/drawimage <image url>
Draws the specified image to the map you're holding. If you want to "save" the picture to the map, you add "-s" to the end of the command. The reason why "save" is written in quotations is because it doesn't actually save the map's picture; it simply saves the URL and it's corresponding ID to a flatfile and is loaded on start up.

/drawanimatedimage <gif url>
Attempts to draw an animated gif image. A little buggy here and there, but it works for the most part! Please be warned that this takes up a lot of bandwith (You're sending anywhere between 0 to 16kilobytes nearly every second!) and that it also is resource intensive!

/drawytvideo <yt-ID>
Experimental. Downloads a video and converts it to a GIF format. See /drawanimatedimage for more information as the same process is used.

/emulategb <rom name>
Highly experimental. Emulates a GameBoy (only GameBoy, not GameBoy Advanced or GameBoy Color) game on a map. Fully integrated, no client mods needed! Click on the chat messages given in chat to control the emulator.

/emuaction <save|load|a|b|left|right|up|down|holdinput>
Simulates input for emulated GameBoy games on a map. Used by the gamepad, you can also use it as a command if you wish. Note that "save" and "load" do not work as of current. Any input button just simulates input. "holdinput" makes the emulator act as if the person is holding down a directional button and directional only.

/clearmap
With a map in hand, this command wipes the image off of it and puts the old Minecraft map rendering back.

/fixmap <id>
A debug command, Caused an issue with a map that psudo-bans them? No worries! Simply get the ID of the problematic map, and type this command in, replacing <id> with the map's id. It's like /clearmap, only this time, you can target maps!

/getmap <id>
More of a debug command, but can be helpful for some, it allows you to get a map by almost any ID. The reason why this is "almost" is because if you try to get a map that is above the number that exists, it merely just goes over and gets the next ID, rather than the one you want. This is something that's within Minecraft that I cannot fix.

Sorry about the delay; I've been distracted with school work.
I am working to fix a majority of the bugs mentioned.
For some reason, TinyURL has a tendency to break image links; try to use something else like goog.le or waa.ai.
and you don't need to pay me; I enjoy maintaining this plugin because though no one ever said it, I felt like everyone had doubted me/believed this was impossible.

Im running spigot (latest build) and when i try to use this plugin i just get a error "A Internal error occurred while attempting to perform this command" It also spammed a error in my console. http://pastebin.com/MdGRT5Rx

I also heard the images dont save after a server reload. i would like that fixed two.

Hey I've got a problem, It's fine rendering images but When I stop the server and restart, all the maps became normal maps. Your plugin verison is ImgMap v1.4.2a for CB 1.7.2-R0.3
bukkit version is craftbukkit-1.7.2-R0.4-20140316.221310-4
